	* Measure accurately		* Measure accurately
	* Don't taste any of the unmixed/undiluted ingredients		* Don't taste any of the unmixed/undiluted ingredients
			I've prepared by doing equipment training, first. I have a graduated pipette with lines every 0.01mL. I'm quite comfortable to give a 0.01mL margin for every measurement I do with it, after playing around with it a bit. The smallest oils (0.07mL coriander and 0.06mL fenchol) I will make dilutions for; the others, I will pipette directly. Between every pipette usage, I'll rinse three times with 95% alcohol.
			* Experiment with taking and dispensing ~0.1mL oil with a precision of 0.01mL.
			* Experiment with measuring and dispensing exactly 9.65 grams of powder. This is necessary for caffeine.
			* Experiment with mixing/diluting in bottles and the volumetric flask.

	~~Use the following list for material training. Only continue when you~~'re ~~comfortable with these.~~		=== Make 7X concentrate and syrup 1 ===
			What we're making:

	* ~~Experiment with taking and dispensing exactly 0.06mL (60 µL)~~ of oil ~~(e.g. olive oil) from a bottle. This is necessary for coriander oil and fenchol.~~		* ~10mL of 7X concentrate - the raw oil mixture
	** If this is impossible, then either:		* ~500mL of syrup 1 - the 7X concentrate diluted in ethanol, used at 1mL per liter of final cola.
	*** Purchase new pipettes
	*** Take more mL of the ~~target oil, dilute with alcohol, mix well~~, ~~then take more mL accordingly of the resulting mixture~~
	*** Or scale up the recipe below
	* Experiment with measuring and dispensing exactly 9.65 grams of ~~powder. This is necessary for caffeine.~~
	* Experiment with mixing/diluting in bottles and the volumetric flask.

	~~=== Make syrup 1 ===~~		Note that the original video recipe makes 100mL of concentrate and then uses 20mL of that for 1L of syrup - the total mixture is the same, but there's a lot more potential waste.
	~~We will make 100 mL of the "7X Syrup", the alcohol-based syrup~~ that ~~contains most of~~ the ~~flavor. The~~ video makes 1L, ~~so all these numbers are divided by 10 below~~.

	Preparation:		Preparation:

	* Warm up/melt the fenchol in hot water before beginning.		* Re-read safety instructions above
			* Prepare a bit of ethanol (a.k.a. food-grade 95% alcohol) and a waste container for pipette rinsing (~15mL)
			* Warm up/melt the fenchol in hot water until fully liquid before beginning
			* Prepare a fenchol solution: 0.5mL fenchol + 4.5mL ethanol, label with "1:10 fenchol dilution", production date and the best before date of the fenchol bottle
			* Prepare a coriander solution: 0.5mL coriander oil + 4.5mL ethanol, label with "1:10 coriander oil dilution", production date and the best before date of the coriander bottle
			Now, we make the 7X concentrate. Take a clean 1L glass bottle. Add the oils in the following order, rinsing the pipette twice with ethanol between each ingredient (begin with 0.5mL pipette, switch to a larger one as convenient while keeping exact measurements):
			* 0.6mL liquid fenchol from the 1:10 dilution
			* 0.7mL coriander oil from the 1:10 dilution
			* 0.12mL orange oil (regular sweet orange)
			* 0.27mL nutmeg oil
			* 0.45mL cassia cinnamon oil
			* 0.8mL tea tree oil (from Australian tea tree, Melaleuca Alternifolia)
			* 3.65mL lime oil
			* 4.58mL lemon oil
			The glass bottle now contains slightly more than 10mL of pre-syrup, since the fenchol and coriander oils were diluted.

	~~Take~~ a 1L bottle, ~~label it "Syrup 1 (7X)" then add:~~		Now, '''very carefully''' fill to 500mL with the ethanol (food-grade 95% alcohol). Absolutely do not overfill, so if necessary do the last part with a pipette. The 500mL mark on a graduated bottle is approximate, but this only affects ''intensity'' of the final flavour, not its character.

	* 4.~~58mL lemon oil~~		Close the bottle tightly and invert several times to mix.
	* 3.65mL lime oil
	* 0.8mL tea tree oil (from Australian tea tree, Melaleuca Alternifolia)
	* 0.45mL cassia cinnamon oil
	* 0.27mL nutmeg oil
	* 0.12mL orange oil (regular sweet orange)
	* 0.07mL coriander oil
	* 0.06mL fenchol (any version of alpha-fenchol should work)

	~~This makes 10 mL~~ of ~~pre-syrup~~.		Label the bottle "Syrup 1 - 2% oil in ethanol - use 1mL per liter of cola", and add the production date and the '''earliest''' best before date of any of the ingredients.

	''The video lets this mixture age for a day or two before diluting in alcohol, but I won't, because (1) I'm concerned it'll offgas significantly into the 1L bottle, and (2) Claude says ageing is fine to do after adding ethanol instead of before (perhaps even better).
